COLOR-DEPOSITING APPARATUS FOR PAPER-MAKING MACHINES.

Application filed'octooer 7, 1926. Serial No. 139,972.

This invention relates to the art of wall paper: manufacture, havingreference more particularly to a type of wall paper generally known astilfany paper, wherein the color effects are incorporated in the paperduring the process of manufacture of the latter, as distinguished fromsubsequent printing, by means of a liquid color, or a number ofdifferent liquids colors, sprayed onto the surface of the Web during thetravel of the latter on the Wire screen in machines of the Four driniertype.

The color spraying apparatus of the present invention is designed toproduce a paper having a variegated or mottled appearance wherein thedifferent colors run into and are blended with each other on thesurface, thus creatinginthe latter regions of different colors which,however,are not sharply defined but, as stated, overlap and blend orshade into each other, creating a variegated cloud effect. i c

Among the objects of the present invention are to provide an improvedand simplified chrome blast apparatus adapted to spray the liquid colorvertically onto the surface of the web, to provide such an apparatuswherein the width of the spray striking the web may be varied throughvertical adjustment of the downwardly directed spraying nozzles or gunsrelatively to the surface of the web, to provide such an apparatuswherein the spray may be delivered intermittently, rather thancontinuously, and during its delivery may have a reciprocating movementrelatively to the web and crosswise of the latter, to provide animproved automatic valveactuating mechanism for the sp 'ay guns, and toprovide an apparatus that may be adjusted to change'the color scheme byatl'ording different relatively timed. movements of the valve-actuatingand controlling devices of different sprayers or groups of sprayers.

Still. other objects and attendant advantages of the invention will beapparent to persons familiar with the art as the same becomes betterunderstood by reference to the following detailed description, taken inconnection with the accompanying drawings, wherein I have illustratedone practical em bodiment oftlie principle of the invention, and. inwhich i Fig. 1 is a side elevation of the color ch positing apparatusand its driving mechanism, showing the wire screen and paper web carriedthereon in cross-section;

Fig. 2 is a top plan View of the sprayers and their actuating devices;

Fig. 3 'is a vertical transverse section taken on the line 33 of Fig. 1;

Fig. 4 1s a detail side elevation of one of the sp 'aying guns and itsactuating mechanlsm; and

Fig. 5 is a diagram, illustrating the general order or arrangement ofdepositing the several colors on the web, and the relation of theactuating cams of the sprayer guns thereto, but without showing theoverlapping and blending of marginal regions of the variously coloredspots.

Referring to the drawings, designates the usual wirescreen'web conveyorof a Fourdrinier machine, and 11 designates the end roll of the machineover which the wire screen passes and by which it is driven. 12designates the paper web which is delivered through the usual flow boxto the screen, spread thereon by the usual slices, and drained by theusual suctionboxes. These parts of the paper machine are not illustratedas they form no part of the present invention.

On opposite sides of the screen 10' are erected on. suitable foundations13 four rec tangularly disposed columns 14, two on each side; andbetween the columns of each pair is a bracket 15 formed at its ends withsleeves 16 slidably mounted on the columns 14 and secured in adjustedposition by set screws 17. On each of the brackets 15 are mounted a pairof pedestals 18 (Fig. 3) formed on their adjacent sides with hearingbosses 19 (Fig. 1) in which. are slidably mounted a pair of parallelrods 20. The columns 14: above the rods 20 are rigidly connected andbraced by longitudinal angle bars 21 and transverse angle bars 22.

Mounted on each of the rods 20 are spaced clamp collars 523 (Fig. 3),and in lateral bosses 24 on the outer sides of said collars are mounteda series of sprayers or guns designated as an entirety by 25, eachterminating at its lower end in a spray nozzle 26. Supportedoncross-bars 27 resting on the horizontal limbs of the angle bars 22 area s ri :in shown as four, of color mani l l v A an, each cquipperlwithoverlying return flow manifold 29. Tapped into the lower sides of themanifolds 28 are faucets 30 each equipped with a valve 31, and dependingfrom said faucetsare hose 32 leading downwardly into the Sprayers25. In the arrangement shown, the hose from a pair of color manifoldson'one side lead into a..ternate sp'rayers in one row, and the hose 82from the two color manifolds on the other side lead into alternatesprayers the other row, so that the sprayers of one row deliver twocolors in alternatiop, arrangement and the sprayers of the other rowalso deliver two colors in alternating arrangement. suspended from therods 20 as by loop hangers 33 (Fig. 1), or otherwise suitably supported,are a pair of compressed air n'ianifolds 3%, from which hose 35 alsolead into the several sprayers. Where the compressed air manifolds aresuspended from the reciprocating rods 20, the open ends of the airl'nanifolds 3d are connected to a compressed. air supply pipe 36 byflexible hose 3'? of suflicient length to accommodate the reciprocatingmovements of the COHlPl'GSSBLl air manifolds.

Rigidly mounted in seats in the upper ends of the pedestalslS' area'pair of bars 38 each formed on its upper edge with a group oiuniformly spaced peak cams 39; the cams of one bar being preferablyoffset substantially midway of the peaks of the other bar. 611 each ofthe collars 28 is an upwardly extending' arm 40 terminating in alaterally offset vertical fork 41 that straddles and extends slightlyabove the cam peaks 39 of the bars 38 The limbs of'eaeh fork ll arethemselves vertically slotted to receive a shaft 42 on which isjournaled roller 43 riding on the upper edge of the cam bar 38. The endsof the shaft 42 overhangthe limbs of the fork, and from theiroverhanging ends is suspended a ll shaped link ll carrying 011 its lowerend a hook d5 that is engaged with a clevis 46 that, in turn, embracesthe trigger d7 of the sprayer gun, the raising of the trigger opening avalve in the gun which perll'llllS the sudden discharge of the liquidcolor and r the air blast furnished from the compressed air manifolds-l-l. As the sprayer gun herein shown is old' and well known and nonovelty is claimed therefor, the structural details thereof are notherein snown. It may be noted, however, that the volume of the blast maybe adjusted by turning an adjusting valve 48 normally locked in setposition by one ormore nuts 49. From the foregoing it will be seen thatas the rollers 43 ride over the cams 39, the triggers of the guns willbe suddenly raised, permitting a charge of colorin g liquid to besprayed directly downwardly onto the underlying web of paper.

The rods 20 may be reciproeated in suitably timed relation to the travelof the paper web by mechanism such as that illustrated in Figs. 1 and 2,as follows: 50 designates a main drive shaft carrying at one end a spurgear 51 meshing with and driving a spur gear on the shaftof the end roll11. Keyed to the shaft 50 is a sprocket wheel 53 which, through asprocket chain at, drives a sprocket wheel 55 fast on a countx-rshaft56. This latter, through bevel gears 57 and 58 drives a shaft 59journaled in bearings (50 on a base plate (31 SHPLIOITiMl on a pier(372. Sn shaft 59 are sprocket wheels 63 which, through sprocket chains(31, drive. sprocket wheels 65 fast on a pair of endwise aligned sh: (i6journaled in bearings 67 on standards (38 on the base plate 61. (in theinner opposed ends of shafts (36 are crank discs (3!) carrying wristpins "(0 herein shown as set 180 apart and having equal throws. Pitmen71 connect the wrist pins with the ends of the rods 20. With this{lli.'?lI1 {'0lllt.T1t, the rods 20 are sin'iultaneously r'eciprocatedto equal extents in op posite directions.

F ig. 5 illustrates diagrammatically the manner in which the variouscolors are sprayed on the surface of the paper web. Assuming that thelatter is traveling in the direction indicated by the arrow, at a pointin the travel of one of the rods 20 (herein indicated as at the end ofits travel) the cams operating the guns carried by said rod serve todischarge the latter, depositing on the paper web the first, third andvfifth rows of color spots, the spots in each row presenting alternatelythe two colors discharged by alternate sprayers. Simultaneously thespots indicated by the second, fourth and sixth rows are deposited bythe sprayer guns mounted on the other red 20, the spots in said rowsalso alternating between the two colors discharged by said second row ofsprayer guns. Atthe top of Fig. 5 are shown the relative positions ofthe two cam bars, when the colors are deposited in the manner abovedescribed. In this diagram the color spots are shown as sharply definedin order to illustrate the principle of operation; but it is to be understood that in actual practice the marginal portions of the spots overlapand blend to a greater or less extent depending upon the verticaladjustment of the sprayer guns above the surfaceof the web.lilanifest-ly, the hi gher the guns are set, the greater will be thediameters of the spots, and the greater will be the extent to which theywill overlap and blend into each other.

The relative positions of the spots, and the ultimate coloring effect orcolor scheme can be widely varied by' either changing the relativepositions of the actuating can'ls or hv varying the reciprocatingrelation of the rods 20, or both; for instance, the wrist pins 70 on thecrank disc 69, instead of being set one hundred and eighty degrees apartso as to effect simultaneous travels of the two rows of sprayers inopposite directions. may he set ninety degrees apart so as to effect asyn chronous reciprocation of the rods. Also, the speed of operation ofthe sprayer guns relatlvely to the speed of travelof the paper web 'maybe varied as, for instance, by providing on the hub of the cam drivesprocket 55 a sprocket of a different diameter, such as the smallersprocket shown at 55, the driving sprocket 53'being shittable along thedrive shaft to register with either of the sprockets 55 and 55. Theseadjustments, together with the vertical adjustability of the sprayerguns, render the apparatus very time ible, and make possible theproduction thereby of widely varying color effects when using a singleassortment of colors.

I have herein illustrated and described one simple and practicalembodiment of the principle of the invention which, in p notice, hasbeen found to satisfactorily effectuate its stated purposes and objects;but manifestly the details of structure and arrangement may beconsiderably varied from those shown without changing the principle orsacrificing any of the advantages of the invention, and hence I do notlimit the latter to the particular apparatus herein presented except tothe extent clearly indicated inv specific claims.
